There seems to be a bug during this mystery quest call "Of Fist Dances and Sweaty Oaths" all of the brawler NPC's just huddled together and do not move around as they use to at lunch day. Below is a video clip showing what's happening now and what the quest looked like at lunch.
Platform is Xbox Series X
Hello there @GLADI8ORDUDE!
Thanks for taking the time to share your report with us, and for including a video. That definitely looks like strange behaviour to me. Just to confirm, are you still able to interact with the brawler NPC to progress with this world event? Or has this issue prevented you from continuing with the mystery?
If you are able to continue with the world event, do the rest of the NPCs return to their previous actions, or do they remain huddled up together?
Thanks! 
I'm glad to hear that progression isn't blocked for you at least, @gladi8ordude. If you continue to progress in the World Event, do you notice this behaviour occurring after each brawl you participate in? Or is it for instance just after the first or second encounter, but not both / all?
Do you happen to have any other videos exhibiting this behaviour, or know of any other players affected by this issue? 
It would help to have additional resources to show the developers to open an investigation with them.
@gladi8ordude
No problem and thanks for the detailed info on this. We'll keep an eye out for further reports.
